This book is the most comprehensive and complete treatise on nucleic acid therapeutic products, including mRNA vaccines, their manufacturing, formulations, and testing for safety and efficacy. Details include cGMP-compliant manufacturing and regulatory filing steps. A new concept of “biosimilar” mRNA vaccine is presented to secure fast approval of copies of mRNA vaccines. Projections of financial plans to establish RNA manufacturing facilities are provided, along with details of supply chain management. Finally, the future of nucleic acid products in gene therapy and •ther newer applications is presented, along with a perspective that all new vaccines will be the nucleic acid type that will further provide first-time prevention of autoimmune disorders. It is projected that both big pharma and start-ups will enter this field, and we can expect significant additions to our drug armamentarium soon.
